Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0015] by figure 1 It can be seen that the present invention is realized through the following steps:

[0016] Compile the system software part;

[0017] Use comprehensive geophysical technology to collect various types of trenchless pipeline data;

[0018] Hierarchical and classified input of accurate 3D trenchless pipeline data into the system;

[0019] System comprehensive debugging;

[0020] In the step "Using comprehensive geophysical prospecting technology to collect various types of trenchless pipeline data": use detection technology to collect accurate three-dimensional information of trenchless pipelines; including: iron trenchless pipelines: use pipeline detection instruments to measure its 2-4 meters For the shallow part of the pipeline, use geological radar to measure its 5-8m middle part, and use a gyro positioning instrument to measure its 8-...

Abstract

The invention relates to a method for establishing a three-dimensional visualization geographic information system (GIS) of trenchless underground pipelines. The method comprises the following steps of: compiling a system software part; acquiring various kinds of trenchless pipeline data by using a comprehensive geographical prospecting technology; inputting accurate three-dimensional trenchless pipeline data into a system in a layering and classification mode; and comprehensively debugging the system. The method for establishing the three-dimensional visualization GIS of the trenchless underground pipelines has the advantages that: various kinds of trenchless underground pipelines are effectively managed, so that underground engineering accidents can be greatly reduced; and the management of underground space resources is strengthened, and the development of a trenchless technology is promoted.

Description

Technical field [0001] The invention relates to the field of trenchless underground pipelines, in particular to a method for establishing a three-dimensional visualized trenchless underground pipeline GIS. Background technique [0002] Underground pipelines are the lifeline of the city. Due to historical reasons, the current urban underground pipeline information is recorded in the as-built drawings and pipeline attribute cards and tables. This manual management method is far from keeping up with the needs of urban pipeline construction. It is difficult to meet the requirements of modern underground pipe network management. In recent years, trenchless pipe laying technology has been widely used in urban underground engineering and underground pipeline construction due to its unique advancement and adaptability. Shanghai took the lead in adopting trenchless technology to implement large-scale urban pipeline construction projects. In the first half of 2007, the trenchless construc...
